A new open-source model of vertical ocean farming created by GreenWave can sequester carbon while growing crops for food, energy, pharmaceuticals, and even cosmetics without any need for fresh water, fertilizers, or pesticides. The kelp grown on the farms absorbs five times as much carbon dioxide as plants grown on land, and the cultivated oysters sequester nitrogen runoff that can cause dead zones and algae blooms that harm coastal ecosystems. The design and species used in the farms provide habitats for birds and ocean wildlife while restoring reefs that rebuild storm barriers.

This post is part of a series on examples of ​multisolving​, or climate-smart policies that simultaneously work to mitigate climate change while providing co-benefits such as the ones described above. The multiple benefits analysis was done using the ​FLOWER framework​.
